WebThe Fourier-transformed extended X-ray absorption fine structure (FT-EXAFS) spectra are shown in Figure 4 for both the pristine (Figure 4a) and hydrated (Figure 4b, 14 wt% water) systems in the crystalline (red), molten (green), and glassy states (blue). We note that the presented FT-EXAFS spectral peaks are shifted by around -0.5 Å due to an ... WebJul 19, 2024 · Extended X-ray absorption fine structure (EXAFS) spectroscopy is an ideal technique for studying the local vibrational dynamics of materials due to its sensitivity to short-range order, correlation of atomic motion and anharmonicity.
